Question

When an electrolyte is dissociated in solution, the van't Hoff's factor ($i$) is :

• A. $>1$
• B. $<1$
• C. $=0$
• D. $=1$

Answer 1

The correct option is A $>1$

When an electrolyte is dissolved in the solution, it breaks into ions and hence the van't Hoff factor will be greater than 1 $(i>1)$.

For example, $NaCl⟶N{a}^{+}+C{l}^{-}$

Here $i=2.$

Hence, option A is correct.
